Double stud pony wall + stem wall transition question for a walk-out basement in Zone 7A.

[jgolden]

I'm trying to figure out how to properly construct a 3 section pony wall in Chief on a stepped foundation.

 

ICF stem wall to slab (purple)

ICF with 2x4 + 2x3 furred wall (yelllow) (hasn't been defined)

double stud wall, 2x6 -> 2x4 -> 2x3 (orange)

yelllow and orange are floor 0

green is floor 1

Cheers!

The orange needs to be floor1.  It's room's floor supplied by level below.  The yellow and blue are floor 0 with floor ~8" below stemwall.  Step your blue as required.

This is a membership only video. I changed it to public for this thread but will change it back to membership after today. give it a watch, it explains a very simple process for this:

Thank you.  My basement is on floor 0.  I'm assuming the reason the furred stem wall in Rabbitt's video doesn't have framing below the slab is it's monolithic?  If I add furred framing to my stem wall it extends all the way down to the footer.

put it on floor 1 and it will make this process a lot easier and more dynamic, that way your stepping happens above your FF and makes use of a stem wall pony wall and your furring wall

Derp!  That finally clicked.  Is there another way to modify my plan other than inserting a new floor above floor 0 then manipulating the terrain Surface at contour?  If not, it's going to be a bit of an effort to shift all manually modified roof, framing, etc.
